Description

You have crash-landed on alien ocean world, and the only way to go
is down. Subnautica's oceans range from sun drenched shallow coral
reefs to treacherous deep-sea trenches, lava fields, and bio-
luminescent underwater rivers. Manage your oxygen supply as you
explore kelp forests, plateaus, reefs, and winding cave systems.
The water teems with life: Some of it helpful, much of it harmful.
